Is there a list on this forum for power adders for the F150? I have the 5.4 engine. I'm fully aware of the basic mods like an intake, exhaust, and then just boosting it. Are there any other possible mods to free up power on a 5.4? And yes tuning I'm aware of that too. Are there lightweight pulleys or anything else like that? I've been looking into converting to an E-fan but how much power does that free up?

 

I know you said you know about tuning but honestly the Edge evolution is the best bang for the buck IMO. $300 for 30hp, can't beat that.
However, you're right on track. Look into Troyer Performance under drive pulleys. Supposedly frees up 13hp with a tune. Also deleting the mechanical fan and switching to an electric fan will also lower the rotating mass and free up some more.

 

Those mods concern me about reliability. That's just me of course but I think tuning is the best option.

 

From what I've read with UDP, you get what you pay for. The cheap eBay sets are scary. The higher dollar ones are reliable and have lots of R&D behind them.
The 5.4L is so detuned it's ridiculous. Get a programmer first.

 

Well, the underdrive pulley's don't really "free up" HP so much as they help slightly with the engines ability to rev quicker due to less rotational mass. The engine still has the same horsepower it did before. The efans are sort of in the same ball park. Personally, I think the Gotts mod intake, a decent cat-back exhaust, and a Gryphon/Diablo with a custom tune is about all you can do for performance without dropping big bucks to get boosted. The 04-06 guys can benefit a bit from headers, but the 07-08 trucks have a better exhaust manifold that doesn't really hinder performance too much at stock power levels.

And of course all the electric fan write ups out there. I've seen one recently with a 2010 F-150 OEM electric fan adapted to our trucks using a Painless F5 controller.

The nice thing about all these mods is that they free up wasted horsepower and torque while at the same time returning a little better fuel economy. However, running an electric fan and water pump, you might need to step up to a higher amp alternator. You should be able to adapt the 200 Amp alternator from the Crown Vic Police Interceptor fairly easily (4.6L V8). Tasca parts sells the 2010 electric fan (it's a dual fan and shroud) for ~$200). I don't remember the exact price but they have the alternator cheap also.

It all just depends how much you're willing to spend. It would be fun to see how much power, torque, and fuel economy you could get out of this engine with these parts.

 

The thing about going "all-electric" with the fans/pumps is that you introduce another item to the system to fail (electric components), and that power comes from increased electric load. So the load increase is combated by the alternator resistance and you lose HP due to the alternator load. I would bet that going to the electric components probably nets you 10HP or less altogether, so $400+ for 10HP isn't exactly a great deal, especially given the consequences of a failed water pump or efan controller.

 

1. Programmer that's able to be custom tuned

2. Billet pulleys

3. Long tube headers

4. Forget the udps....go supercharged

 

Bingo, unless OEM no thanks

 

Thanks for the input guys.

 

Is there a write up for removing the mechanical fan?
